摘要:

科技竞争时代,技术机会的识别和挖掘为科技研发方针和政策的制定奠定重要基础。本文提出基于链接预测的量化方法,将技术机会识别任务转化为技术元素之间是否能产生共现联系的二分类问题,为技术机会识别提供详细的数据辅助和支撑。获取隐私保护领域的专利数据,构建IPC 共现网络并训练图神经网络模型GraphSAGE,得到链接预测分数后分别从强化型、新生型和衰退型链接3 个角度识别持续发展的技术机会、突破创新的技术机会以及寻求转型的技术机会,最后基于识别得到的技术机会展开分析并提出建议。

Abstract:

In the era of scientific and technological competition, the identification and mining oftechnological opportunities lay an important foundation for the formulation of scientific and technologicalR&D guidelines and policies. A quantitative method based on link prediction is proposed to transformthe task of technological opportunity discovery into a binary problem of whether there can be cooccurrencelinks between technological elements, so as to provide detailed data assistance and supportfor technological opportunity identification. Obtaining patent data in the field of privacy protection,constructing IPC co-occurrence network, training GNN model GraphSAGE, and after obtaining thelink prediction score, the authors identify the technology opportunities for sustainable development,breakthrough and innovation and the technology opportunities for transformation from the perspectivesof enhanced, newborn and declining links respectively. Finally, they analyze and put forward suggestionsbased on the identified technology opportunities.
